Reliability and Lifetime of Multilayer Piezo Actuators

Monday, January 18, 2010Three essential factors affect the lifetime of piezo ceramics in positioning applications: Humidity, operating voltage and temperature.
PICMA® multilayer piezo actuators are based on a special PZT (lead zirconate — lead titanate) ceramic, formulated to combine the desired characteristics for motion control such as high stiffness, low electrical capacity, high specific displacement, low load and temperature dependence with exceptional reliability and long lifetime.
